1. STRUCTURE AND FUNCTIONS OF LIVING ORGANISMS

2. CELL
Basic unit of all living things

3. NUCLEUS
Command center of the cell; contains information of how the cell will behave, grow, or divide

4. Organism
an individual structure or form of life

5. UNICELLULAR Single cell organisms, such as bacteria and fungi
Only purpose is to survive

6. MULTICELLULAR Many cells working together
Contains a nucleus and a surrounding nuclear membrane

7. Complex
consisting of many different and connected parts
Multicellular organisms are complex

8. HUMAN BODY SYSTEMS Respiratory System (nose, trachea, lungs)
Circulatory System (heart, blood, vessels)
Respiratory System (nose, trachea, lungs)
Skeletal System (bones and joints)
Muscular System (voluntary and involuntary muscles)
Digestive System (mouth, esophagus, stomach, intestines)
Nervous System (brain, spinal cord, nerves)

9. CIRCULATORY SYSTEM Body’s main transport system
Made up by blood, arteries, veins, capillaries, and heart

10. RESPIRATORY SYSTEM
Exchanges gases between the air and blood

11. SKELETAL SYSTEM
Frame that helps living organism their shape and protects organs
Endoskeleton- bone (hard tissue)
Exoskeleton- shell that protects the inside

12. MUSCULAR SYSTEM
Muscles that can lengthen and shorten, which creates movement in the body
Voluntary muscles are controlled by you
Involuntary muscles move without conscious thought (heart beating, lungs operating, digestive system)

13. DIGESTIVE SYSTEM
The process which food is broken down into smaller pieces and then chemically changed to obtain the necessary nutrients the body needs to survive (Goes from mouth to esophagus, to stomach and then intestines)

14. NERVOUS SYSTEM System that controls the bodies activities Brain
Spinal Cord
Nerves
